Hmm, I'll see if I can find out what Bletchley Park did in wartime - aside
from several Colossus machines, there was a significant
teleprinter and
punched-card presence, too.
I seem to remember that the main floors in H Block (now housing the computer
museum, and where - IIRC - 4 Colossus machines used to live) are solid
concrete with a central channel for wiring and power, but I don't know if this
channel was put in after the war or when the building was put up.
(Of course that's all 1940s, so not significantly before the 1950/60 dates
already being talked about - and punched-card equipment had existed for a long
time by then)
